Hydroxypropylkylylulose, oo sidoo kale loo yaqaan hypromellose iyo unugyada hydroxypropylykyl ether ether ether, waxaa laga sameeyaa unug jilicsan oo suuf ah oo si gaar ah loo adeegsado xaaladaha alkaline.
Farqiga:
astaamo kala duwan
Hydroxypropyl methylcelrellose: cadaan ama buluug-cad ama geedo yar yar, oo ka mid ah noocyo aan inic-ka oo kala duwan oo isku-dhafan, sheygaani waa sym-synthetic, poly poly poly.
Kariimka hydroxyetyl waa mid cad ama jaalle ah, fiber ama budo aan sun lahayn ama shey adag, sheyga ugu weyn ee celyer-ka waa alkalide celtherity, oo ah unug aan isicil ku milmay.
Isticmaalku wuu ka duwan yahay
Warqadda rinjiga, hydroxypropylykhelulosose waxay leedahay xabad wanaagsan oo biyo ah ama koollo dabiici ah sida dhumuc weyn, kala firidhsan iyo xasilin. Polyvinyl chloride waxaa loo isticmaalaa sidii buugaagta rinjiga si loogu diyaariyo polyvinyl chloride, oo si weyn loogu isticmaalo maqaarka, waxyaabaha waraaqaha ah, ka-hortagga khudradda, dhaarta iyo khudradda iyo warshadaha kale.
Hydroxypropyl methylcelrenose: ku dhawaad yareynta ethanol etherad, ether, acetone; Xal-xumada sallaanka ah ee hufan ama qashinka lagu isticmaalo biyaha qabow, oo si weyn loogu isticmaalo jaakadaha, khafiifka, dheecaanka, dheecaanka, sunta cayayaanka, waxyaabaha sunta cayayaanka, soo kabashada saliida, soo kabashada saliida iyo warshadaha dawooyinka.
Xoolaha kala duwan
Hydroxypropyl methylcelrenose: ku dhawaad yareynta ethanol etherad, ether, acetone; ku milatari xalka daruuriga ee daruuriga ah ee daruuriga ah ee daruuriga ah ee biyaha qabow.
Kariimka hydroxyetyl (HEC): Waxay u diyaarin kartaa xalka noocyo kala duwan oo isku-darka ah, waxayna leedahay guryo wanaagsan-milix wanaagsan oo lagu diro elektrolytes.
